IMPROVEMENT IN MACHINES For PICKING'AND CLEANING woor, tc.

Specification forming part of Letters Patent No1. 4 [,936, dated March 15, 1864.

following to be a full, clear, and exact descrip-` tion of the said invention, reference being had to the annexed drawings, making part of this specioation, wherein l E Figure l is avertical longitudinal section of my said machine, and Fig. 2 is an elevation of the' feeding end where the ber is supplied to the machine.

Similar marks of reference indicate the same parts.

In Letters Patent granted to me January 6,

`1863, a cylindrical rotary feeding-table is set forth, and in Letters Patent granted to me l, June `17, 1862, an arrangement of .cylinders is shown in which both sides of the ber are exposed to the action of beaters or strippers for removing burrs and other foreign substances.v

The nature of my present invention consists in arevolving feedingcylinder,in combination with a receptacle into which the cotton, wool, or other ber is placed, and from which said cylinder draws the ber to the extent necessary for lling its card or other teeth with such ber, and I combine therewith avibrating or oscillating comb that detains, keeps back, and evens the ber on such feeding-cylinder. The feeding-cylinder is provided with a shell surrounding a portion of it, and from the said feeding cylinder the ber is taken, pulled apart, and gradually opened by toothed rollers acting at theedge of such shell to draw off and loosen the ber and allow dirt to fall out, and from thence the ber is exposed to a cleaning operation on both sides, according to my said patent of June 17, 1862. By this arrangement I make use of the rotary feeding-table :similar to that shown in my patent of January 6, 1863, combined ,with a hopper or receptacle,

pulling the same simultaneously in different directions, and with a comparatively slow motion, thereby avoiding the difculty hereor other ber that is to be operated on.

tofore experienced of cutting and breaking the ber in picking and cleaningthesame. At the same time the burrs and foreign substances are loosened and easily fall or are knocked raway by the strippers, because they'are not compressed into the wool or other ber by :feed-rollers, tc. Y

In the drawings, a is a frame-work of any yusual kind, on which the receptacle or hopper ,b is placed. This is formed of a nearly parl alle] sidedbox, the front of which should be of slats, as seen in Fig. 2, in order to morev readily examine the quantity of ber in such receptacle.

c is an inclined bottom board to the receptacle, which is above the feeding-cylinder d, that is formed with card or other` suitable teeth projecting from the surface thereof in ,such a direction that said teeth will, as they revolve iu the direction of the arrow, draw down from the receptacle such cotton, wool, In order to prevent too large a quantity of ber passing in bythe said cylinder d, Iemploy the vibrating or oscillating roller e, with a comb, 1, afxed t0 the same, which comb removes the surplus bers from the'teeth ofthe cylinyder d and detains them in the receptacle b.

The depth. of the teeth on the cylinder d, and the speed or motion given to such cylinder, will determine the amount of ber supplied into the machine with great accuracy, and the parts may be driven by gearing or belting of any usual character. I prefer that the vibrating comb be moved by a crank-arm, 2, to which a positive motionis given by a pitman to a crankpin describing a circle with a less radius, and driven by one of the other shafts of the machine with the required speed.

Beneath the feeding-cylinder d is the shell f, that holds the ber to the teeth and prevents such ber falling off during the slow movement ofthe cylinder. n

g is a toothed cylinder parallel to d, and la is a similar cylinder below g, both having teeth standing away from the inner or back edge of the shell f, and both cylinders being rotated by competent power in the direction indicated in the arrow pulls the ber off of ard' out from the teeth on d, separating and loosening any lumps, and the edge of the shell f aids in this operation by detaining such lumps until they gradually pass above said edge as of the said cylinders.

m is atoothed roller more thoroughly to clean the feeding-cylinder d and convey the ber to the cylinder g.

The ber upon the cylinder gis subjected to `the action of the beater or stripper i. which knocks ofi' and removes any burrs or lumps, and such lumps fall orare thrown on the fluted roller k below the cylinderh, which,revolving slowly, carries such lumps beneath the cylinder h, and any fibers are taken by said cylinder and carried up again to the cylinder g, which, traveling tastesastrips this cylinder l1.. Any dirt and burrs that fall on theuted roller k are out of the reach of the teeth on l1. while in the flutes, and pass on and fall out;

From the cylinder g the ber is taken oft' by the cylinder l, which, being driven faster than g, draws oil' the ber, at the same limeloosening it and presenting theotherside of the sheet or` bat to the action of the stripper m, that acts the same,in removing any burrs from the ber,

as the device described in my patent of June 17, 1862. .y r is a receptacle for any burrs re moved by the stripper m.

From the cylinder Z the ber is takenaway by the blower u,`that is fitted with slats 3 3, armed with strips of card-teeth, so as to entirely clean the cylinder Z and blow the ber away; andI nd in practice that such cardteeth do not det-ain the liber like abrush; neither do they become clogged and obstructed, but allow the fiber to pass off from their points with ease, as driven away bythe blast of .ai r and centrifugal force.

A grating, o, is provided below the blower to allow any particles of dust, Sto., to pass away, but to detain the ber until `it arrives at the delivery-mouthfp. q is the cover or case to the blower.

The gear-wheels, pulleys, belts, &c., for giving motion to the different parts may beof any desired character, and do not require fur ther description. l I do not claim a hopper from which ber is taken by a toothed cylinder, as this is common with cotton-gins. toothed cylinder isemployed to open,`sepa rate, and convey the ber away from seeds or foreign substances, and does not act in the capacity of a feeding device to supply a regulated quantity to the `cleaning mechanism; and I do not claim returning the bersthat may fall with ythe burrs to the cleaning-machine to prevent the Waste of such ber. y

What I claim, and desire to secure by Let-` ters Patent, is- I 1. A toothed cylinder, in combination with a receptacle or hopper to act as a feederto carding, picking, and cleaning machines by conveying to such machines the bers that are seized by` and surround the teeth of such cylinder, substantially as specified.

2. A vibrating or oscillating comb or detainer, in combination with the said feeding,

cylinder and receptacle, as specilied.

3. The'uted roller lc, in combination with the toothed cylinder l1J and stripper z', for the purposes specified.

strippers rand m, arranged substantially as specified, in combination with the feedingcylinder d and shell f, for the purposes and as specified.

In witness whereof I have hereunto set my signature this 15th day ot' September, A. D. 1863.
